S HEATING APPARATUS.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed November 9, 1907. Serial No. 401,481.

To all whom it may concern:

Be it known that I, THOMAS B. J ARVIES, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Gas Heating A paratus; and I- do declare the following to e a full, clear, and exact description of the invention, such as will enable others skilled in the art'to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to gas heating apparatus, and more particularly to an apparatus of that class for use in combination with a hot air furnace.

It is the object of my invention to secure, as nearly as possible, a perfect combustion of the burning fuel, and to provide an arrangement of parts which will not only secure such combustion, but will also so dispose the heat as to secure the best results therefrom.

A further object is to provide the improved details of structure which will presently be fully described and pointed out in the claims,

reference being had to the accom anying drawings forming part of this speci cation, in which like reference numerals refer to like parts throughout the several views, and in which:-

Figure I is a view, in side elevation, of a furnace equipped-with an apparatus conhaving side and bottom s ots 6.

structed according to my invention. Fig. II is a central, vertical, sectional view of same. Fig. III is a horizontal sectional view on the line IIIIII, Fig. II. Fig. IV is an enlarged detail view, in front elevation, of the furnace rate, burner, and fuel supply arts. Fig. t is an enlarged detail view, in si(, e elevation, of one of the burners and mixing chambers. Fig. VI is a front view of similar parts, in central vertical section.

Referring more in detail to the parts :-1 designates the outer casing of a hot air furnace, of any ordinary construction, which is provided with the usual feed door 2, and an opening 3 to the ash pit.

Nithin casing 1 is a fire pot 4, preferably of cast iron, from which is sus ended a grate 5,

Opening from the fire pot, near the top, and pro ecting through casing 1, is the smoke pipe 7; and the air chamber between the are the heat conducting opening from fire pot and easing,

pipes 8, which may lead to apartments in I the building within which they are located. Leading from a suitable fuel supply, (not shown) is a feed pipe 9, which pro ects into casing 1 beneath grate 5, and is provided with an end cap 10. Leading from the main feed pipe 9 are branches 11, of any suitable number, which are turned upwardly at their ends and pro'ect through the bottom of the grate, through the slots 6 if desired, and terminate slightly above the level of the tops of the slots in the sides of grate 5. Branches 1 1 are provided with the mixing chambers 12,

preferably located below the grate bottom,

through which air is admitted to the branch pipes, for the purpose of providing a combustible fuel mixture.

13 designates a diaphragm which fits within the grate, preferably above the side slots, and havin perforations through which the upper cm s of branches 11 project. On the upper end of each of branches 11 is a flame spreading hood, comprising a body portion 14, having a channel of slightly greater diameter than that of said branches, and an inturned flange 15 which surrounds the fuel vent 16. Projecting upwardly from near the edge of the hood to is a baffle plate 17,which is inclined forward y overthe fuel vent, and flares laterally as indicated in the drawing.

18 designates a base flange, preferably integral with the hood, which is adapted to rest on the diaphragm 13 when the hood is in position on t e branch end.

When installing, the fuel feed pipe is connected with the furnace and the individual burner branches projected through the bottom of the grate, as described. The diaphragm 13 is then inserted in the grate and adjusted so that the portions of the branches rojecting thereabove will be of suflicicnt lieight to enable the ends of the pipes to rest against the inturned hood flange, and the hood base flange to seat on the top of the diaphragm; the pipe branches being preferably cut to the right length to accomplish the result noted when a standard diaphragm is used. After these parts have been adjusted, a hood is placed over the end of each pi e branch, w1th the baflle plate 17 preferab y directed outwardly, in order that the flame may be directed against the side of the fire pot. When the burners are lighted, the flame, which is usually discharged under considerable pressure, contacts withthe baffle plate 17 and spreads, giving all of the fuel particles an opportunity'to ignite, and in that Way securing much better combustion than could be had should the fuel be disthrough the mixing chambers and fuel pipes, thereby securing a better combustlon of the fuel, and a more intenseheat.

While I have described my invention as applied to a hot air furnace, its adaptability for use under boilers, or with steam and hot Water furnaces is obvious.

Having thus described my invention, What I claim as new therein and desire to secure by Letters Patent is 1. In a gas heating apparatus, a fuel feed pipe having a discharge port, a hood seated on said pipe over said port and provided with a fuel opening, and a plate integral with said hood extending upwardly and laterally over said fuel opening, for the purpose set forth.

2. In a gas heating apparatus, a fuel feed pipe having an interior channel and provided with a discharge port, a hood loosely seated on said pipe over said port and provided with a fuel opening of less diameter than the pipe channeL-and a plate extending upwardly and l laterally over said fuel opening, for the pur pose set forth. y

3. The combination with a fuel jfoed pipe, of a hood comprising a channeled body portion adapted to seat over said pipe and aclosed end by which said body is supported on said pi e,'said end portion having an opening of ess dlametcr than the pipe chane nel, and a laterally flaring plate projecting from the side of said hood over the hood opening, substantially as set forth. I

In testlmony WhereofI affix my signature in presence of two Witnesses.
